Fig 2. Correlation and scatter plots of diffusion indices derived from normal-appearing pyramidal tract (NA PYT) versus PYT lesion volumes. Scatter plots are shown of (A) fractional anisotropy (FA), (B) directionally averaged diffusion coefficient (Dav, x 10-3 mm2/s), (C) axial diffusion coefficient ({lambda}1, x 10-3 mm2/s), and (D) radial diffusion coefficient ({lambda}23, x 10-3 mm2/s) versus PYT lesion volumes (mm3).
